| Abstract: | Silicone pressure-sensitive adhesives prepared from a platinum-catalyzed, high solids silicone composition are described. The adhesive compositions consist of an MQ siloxane resin, vinyl-and hydride-terminated silicone fluids, and a multifunctional vinyl silicone crosslinker. In this study, multifunctional vinyl silicone crosslinkers of various structures, including linear polymers, T, TQ, and Q resins, were prepared and evaluated for their effect on the adhesive properties of cured silicone pressure-sensitive adhesives. Additionally, the activity of these multifunctional vinyl silicones in hydrosilylation reaction was investigated. © 1994 John Wiley & Sons, Inc. |
